Buckley, who arrived at the premiere in a rose-printed dress, said she was drawn to her role for her “tenacious courage and bravery to go after a dream against the limit of what the world is telling her she’s allowed to dream of”.

She added: “For me it was a prison break film for all the women in it, to dream big.”

Buckley also admitted she had no interest in country music before making the movie, saying: “To be honest I thought country music was hick and I had absolutely no relationship with it whatsoever.

“I had done a bit of blues and jazz but then I was opened up to the storytelling of country music and the direct honesty of the lyrics and the simplicity of the human heart and that was a gift.”
